I’d imagine a Pete/STA would be pretty easy , and we already know the Pete flies well …
Just in case you missed it we already transformed a Pete into a Piper PA-25 … cropduster… Flew Great too …everything else the same except the profile of the fuselage slightly altered…
If you’re doing a profile fuselage , then you can do profile wheel pants too , like on the Gee Bee profile ...

i was wondering if anyone knows of plans for a foam p-51 large enough to handle a, 15 size 1250Kv motor left over from a plane my brother destroyed? it would be cool to do foam board, but if i have to wire cut ( which i have never done) i think that would be cool to try as well
